What a bad game! Graphics, sound and feeling are all great but gameplay is beyond bad and frustrating. What looks like a tower defense kind of game is actually a puzzle where (after the first few easy missions) you need to deploy the right units, in the right spot and use the right abilities at the right moment. So yeah, there’s no much strategy involved, just figure the right setup or else you lose. Unless you’re overpowered and can brute force your way to victory. You obviously won’t have the right units or they won’t be properly leveled but fear not, the cash shop is there to help you: for insane amounts of $ you can play the gacha trying to get the units and buy resource packs to level them. /s Stay away from this pretty looking cash grab of a game. Oh, the game will give you an S (good) unit if you manage to complete increasingly difficult missions during the first 14 days. In order to achieve this you’ll have to turn the game into a second job or, you’ve guessed it, cash shop to the rescue. :) Most of the units are very attractive, provocatively dressed ladies, as the game has a mature rating, they really are using every trick to get you playing and spending.
